🔩 Phosphor Bronze Fasteners Manufacturer, Supplier & Exporter in India
DotsFasteners is a renowned manufacturer, exporter, and stockist of Phosphor Bronze Fasteners in India, offering high-performance fastening solutions globally. Our fasteners are designed for industrial-grade strength, excellent wear resistance, and anti-corrosive properties, making them ideal for demanding mechanical, marine, and automotive applications.
Made using premium-grade C54400 phosphor bronze, these fasteners exhibit excellent spring qualities, low friction, and high fatigue resistance — essential for high-load or vibrating environments.
✅ What are Phosphor Bronze Fasteners?
Phosphor Bronze is an alloy primarily composed of copper (Cu) with 3.5–4.5% tin (Sn) and 0.01–0.50% phosphorus (P). The addition of phosphorus enhances the alloy’s toughness, fatigue strength, and wear resistance while maintaining excellent conductivity.
Phosphor Bronze Fasteners are widely used in applications where non-magnetic, spark-resistant, and corrosion-resistant hardware is essential.
